To all whom. it'mwy concern: 1 7

Be it known that I, RODERICK W. DAVIES, a resident of Avonmore, in the county of Westmoreland and State of Pennsylvania, have invented a new and useful Improvement in Wire-Glass Machines; and I do hereby declare the following to be a full, clear, and exact description thereof.

, My invention relates to a machine for making. rolled sheet glass,-sucl1' as plate-glass, ribbed glass, prism-glass, and the like.

The object of the'invention is to provide a machine whereby the manufacture of such glass is greatlyexpedited and facilitated, so as to increase the output and cheapen the product. v

The inventionhonsists, generally stated, in providing a series of tables upon whichthe glass is formed and having said tables mounted upon a carrier which will carry the same in succession to the pressure roller or I rollers which form the glass on the table, said platform bein intermittently driven, so that the tables areTield stationary while pressurerollers form the glass thereon.

The invention also consists in certain de tails of construction, such as means for applying wire-trellis when making wire-glass, means for ad'u'sting the same, means for cooling the ta les, andother details which will be hereinafter described and claimed.

in the accompanying drawings, Figure 1 is a plan view of my improved machine.

Fig. 2 is a side elevation thereof. Fig. 3 is a section on. the line 22, Fig. 1., Fig. 4 is a vertical section through the rollers and table,

showing the, parts on an enlarged scale; and

Figs. 5 and 6 are detail views 'ofjo f th Water-valves. r a

My machine includes a suitable pressureroller. and casting-tables. Imakeuse of a plurality of tables 1' fin connection with a single roller2. The tables 1 are mounted upon a suitable carrier 3, which-will carry the same succession into positiontocooperate with the roller 2. This carrier 1s shown as a circular platform built 11 .ifl' .8,I1y suitable way'and'provided with ra al a'rnrs or beams a,jconne'cting with a hub 5, secured to a cen- 'tral' shaft" 6, mounted in a stepped "bearing; 7. The platform is also provide with a's uite abie'number of wheels 8, rumiing on a circu rotated by any suitable mechanism, the drawings showing the same provided with an annular rack 10, which is engaged by the pinion 11 on a power-shaft 12. This shaft may be driven by any suitable mechanism, such as the electric motor 13. The driving mechanism will be arranged. so as to rotate the platform 3 intermittently, such as providing the same with a clutch 14, whereby the platform may be started and stopped when desired. v

The tables 1 are secured to the platform 3 in any suitable manner so as to be carried 2, and the carrier will then be stopped, so that the tables will be stationary while the glass is being rolled onto the same.

The roller 2 is carried by a suitable carriage 16,'moving in overhead guides 51' ways 17, and will be traversed longitudinally of the tables 1 by any suitable mechanism, such as thehydraulic cylinder 18, havingits pistonrod 19 connected. to the carriage 16. The roller 2 is mounted in suitable hangers 20, depending from thecarriage 16, and has its bearings or boxes 21 mounted in slots 22 in said hangers, so that said roller can move vertically to adapt itself to various thick I nesses of glass. The roller is held against the glass by its own weight.

The roller is made hollow, as indicated at an inlet-pipe 24 and to the opposite journal um. The inlet-p'pe is able'cut-off valve 26. 4

The tables 1 likewise are so constructed that they can be cooled, being hollow, as indie provided with a suitmeans'of a pipe 29, to the central shaft 6, the

gv ide' with'asuitablegutter (not shown) ior lar track 9. This platform may be driven or cated at 28. Each table is connected, by

latter being made hollow and having con-.

around thereby. These "tables will be carried into position to be acted on by the. roller 23, and to one journal thereof is connected an outlet-pipe 25 for a suitable cooling medi jchar es on thefloor','the latter being {we turn is carried by hangers 42, de ending conducting away the water. It is :not necessary that the cooling medium to the tables be en plied during the entire period of ,their' trave with the carrier 3; but it is necessary thatsaid medium be supplied to the, tables.

during thetime that the hot glass is being rolled down onto the tables. To re 'ulat'e the supply of cooling 'medium to the ta les, each of the pipes 29- is provided with a valve 33,

whichis so constructed-that-it will automatically close and normally remain closed. As shown in the drawin s, each valve is provided with a spring 34- 'or closing the same.

The valve-stem passes down through a stuff-' ing-box'and at its lower end carries a roller 36, which'is adapted to run up onto a cambar 37, located in 'such position that the period of the trave of'the tables.

valve will be held 0 en during the re uired en said roller runs off the end of the cam-bar, the valves will automatically close.

The invention so far described is capable of making all forms of plate, ribbed, and For making the former the table, and rollers will be ro'vided with I smooth faces, while for making ribbed or prism glass the table or roller, or both, will be provided with suitably-ribbed or otherwisesha ed faces.

,or making wire-glass means are provided.

for applying a trellis to the glass. .This'is accomplished by connecting to the carriage 16 a suitable support having a roll of trellis.

As shownin the drawings, the trellis roll 40 is mounted in-a suitable box 41 which in from the carriage 16. The front en of the tableis provided with suitable means for attabhingthetrllis thereto, such as the clamping-bar 43, which may, be operated by any sintable means, such as the cams 44, having op'eratmg-handles 45, To maintaina sufficient tension on the trellis, the roll 40is put under suitable friction, such-as by means of a sprmg 46, bearing on said roll. ,The' trellis passes from the roll and underneath a gage ar or roller 47, which-will hold the same the proper distance above the table 1. This v Y gage baror roller 47 is vertically adi'nstable, 59.

so as to vary the position of the trel is in the glass or adaptthe same to glass of various thlcknesses. This adjustment may be ef- "fected by various means, the drawings showthicknesses these ingradjusting-screws 48 of the ordinary t e.

he batch of glass is poured onthe ta le"1 in front of the roller 2 and between the. same and the box 41. A suitableglm 49 is pro'- vided for" confining the. molten glass." .In order to prevent overheat ofthefbox 41, the front wallthere'ofis e double or hollow, as indicated at 5,0 ":1 The roller 2 runson suitable guides .or stripsiezonthe ed '6 of th table 1, and in order to'make'glassflo various guidesor strips are removable, as s ordmari y the ease.- The rear end v of the table is provided with aknife 53,Which passes over the edge of 'saidknife.

The operation of the machine is as follows: The platform 3 is intermittently rotated to carry the tables 1 around in a circular course. When a table approaches the roller 2, the carrier is stopped and a batch of glass is poured roller is then traversed by admitting pressure to the cylinder 18, thus rolling the glass down upon the table. The platform 3 is 'out of the way and bring the nexttable into position for receiving the batchof glass. When the roller- 2 hasbeen retracted and said table,the roller is again traversed over the'same. In thisway the tables are brought in succession into position to be operated on by the roller 2, so that the rolling of the different sheets of glass can take place in very quick succession. .The glass is removed from the tables at any convenient point in the travel of the tables 1'. By having a series of largely, increased over existing machines.

"thereon, this being accomplished by 'the the box in front of the roller 2, and'the endof the table. The batch is then poured onto the trellis and onto the table, and when the carriage 16 is traversed the roller embeds the over the knife at therear end of the table trellis is cut ofi.
